On CP+ 2013: Interview with Olympus' Toshi Terada article (242 comments in total)

Their perception of where the battle is right now, being:
"it can offer a big difference from smartphones"
pretty much explains the recent 1/2.3" xz10 introduction (and Fuji's small sensor mega zooms as well).

Perhaps listening to what users want would better help compete, expand market share... and the smartphone wouldn't even be an issue.

the only masterpiece here is Ella herself!

I think it was with a Nikon P7000 if anyone is wondering.

Trollshavethebestcandy: I find it interesting naysaying 400% pixel peepers demanding perfection from a revolutionary introduction 1st generation new technology (to consumer cameras) adapter that does so much at only $600. dont buy it if you are so righteously offended that smaller sensors can use FF lenses and get similar results and then some. What a bunch of wet blanket elitists. Go have fun with your gear and applaud new technology and the people who have the courage and brains to create something worth while. Geez! if there was no innovation you would all still be using peep hole cameras! you lot must be quite the life of the party. What have you created? My hats off to the men behind this. I cant wait to use one. Some valid points about some issues but you dont have to use one. Manual focus primes on this and vor video will be a boon. This will only get better. Where was digital photography 10 years ago? look at it today!

Well said @fmian!

In reply to:

intensity studios: I would definitely buy one when it makes it to $100-$200 price point.

As it is now, if you buy a mid range DX camera for $1000 and add this is comes out to about $1600, for which you could buy a low-end or used full frame, which would be better than an adapter.

But this item definitely could be useful for a lot of people. It just needs to hit the right price point. Remember, most people use DX because of limited budget, but to get your wide angles actually be wide would be very useful

Isn't it ironic, that the argument being used, is that you can use those very expensive old lenses, that give you such amazing image quality, but to see that quality disappear? may as well buy that cheap new lens or two that was missing from your new camera arsenal, for the $600, and still have less CA and fringing than a great lens on a SB.

9VIII: Mirrorless cameras now have a reason to exist.
APS-C is cheap compared to full frame, but gives up clarity and light from the smaller sensor. If Canon were to put one of these on a EOS-M that doesn't suck, people would have legitimate reason to chose EOS-M over an equivalent SLR.

What happens if you just take a legacy lens and move it closer to the sensor (of a mirrorless, for example). Do you just lose focus to infinity, or is it more severe than that?

garyknrd: As a Canon shooter I am ready to take the plunge with Nikon. Canon is stagnant in the sensor department and Nikon and Sony are kicking it big time.
I am going to wait one more year for lenses and one more camera update. Then I am there.
Great job, Nikon

why would you want to downgrade from apsc to this?

kayone: Math is wrong on the 42.5 caption, should be an 85mm f 2.4 equivalent

don't forget that while one calculation is linear (ie: 42.5 vs 85 (or 90 as they wrote in the article), the surface area (of the opening) decreases by the square root, thus, the relative aperture change is far greater than the extension.

In reply to:

Krich13: Could you please clarify the testing procedure? When the Canon lens is tested at say f/1.4 with Speed Booster, is the "boosting" effect already taken into account? In other words, is the lens itself stopped down to f/2, and "becomes" f/1.4 using the adapter? Or is it used wide-open at f/1.4 and effectively turns f/1 with the adapter? Later in the review you discuss the 40 mm lens at f/2, so it seems that the effect of the adapter is taken into account, I just want to be sure.

The same question about the f/8 test. Are both _lenses_ set to f/8 or both _systems_ (including the adapter) set to f/8?

Thank you in advance

"For example, comparing NEX-6 and EOS 6D certainly puts the SB at a huge disadvantage."

You need something to compare it with, and that has to be something very good, if you want to be able to measure just how much CA etc is actually caused by the SB.

Taikonaut: On older lens that was developed during the film days such as the EF 85mm f1.8 and EF 50mm f1.4 corner sharpness, vignetting and CA is much more pronounced. With more modern lens made from the digital era it fits the Metabones more perfectly and optically performs much better.

It's what he does best! lol

Let's not push it... the M isn't exactly the best of the mirrorless, if one would trust the reviews. ;)

In reply to:

plastique2: It is really about time to change the term used in the English speaking photography community for the capability of a lense to let through more or less light. The term "speed" is absolutely misleading. We from non-english speaking countries have to endure the torture of reading photography related material translated from English by people who have no clue about photography.

This can look like this (my attempt to make an impression of what we actually have to read in our language - because someone translated literally something he didn't understand what it's about - but then who can blame them given the English text):

"This lens is very fast, although it isn't fast at all."

When we say in our language that a lens is fast, it always relates to it's ability to perform any kind of mechanical operation in a short time period. Yet when we wan't to address it's quality of light gathering, we use two words, the translation would be: "light power". Doesn't that make more sense?!

Totally agree with you, and BTW it doesn't really make any more sense in the English language either! Another term often used is "bright" lens, and that is what should be used all the time (especially on photography websites catering to an audience of varying levels of experience). Just because a bright lens allows you to use faster shutter speeds isn't a good reason to call it a fast lens IMO.

In reply to:

davidbindle: So if the adapter was used on a traditional slr APS sized sensor - would the AF performance improve?
I have both a 5DMKII and a 60D. At times, I only want to bring one camera and that could often be the 60D especially if I want more reach from my 70-200 2.8. But if I could get 25.6mm at the wide end of my 24-70 2.8 (and at f2.0) that would be pretty cool!

I wonder if they even could make a pure Canon FF to Canon APS adapter. Perhaps this is an impossibility because they can only work with mirrorless cameras??

Just wondering

they mention in the article that AF performance decreases

Timmbits: Forgive me for saying this, but the purple fringing, chromatic aberration, is much worse than the text suggests (which uses words like "impressive") and reading "You'd be hard-pressed to find significant difference between the two files in the center of the image"... well I beg to differ! Even at center, one image has black, while the other has CA even at center, because there is no black: everything's purple!
At this price point, we have the right to have certain expectations.

@Viking: that is exactly my point: an APSC camera will set you back a thousand bucks, give or take, and the cheapest FF is what, about $2k for a D600? I'd much rather get the FF.
But staying on the apsc topic, I buy used legacy lenses on ebay (have a nice Minolta 50mm f1.4) that cost me $100, and the adapter $20 (no optics, just physical adapter). I'm now on the lookout for a nice ~30mm f1.4 as I own the samsung 30mm f2 but want to do better.
Now the $600 question: how many lenses, used, can I buy, for the price of this optical reducer that gives me mediocre image non-quality?
I just think it is a rip-off.
How long will it be, before the chinese are selling adapters like this, for the same price they sell their 2. and x0.45 adapters? (which is around $50) ...and judging by the image quality of this one, it won't be hard to match.

Just saying.

Richard Murdey: 1:1.8-2.7

Wow. That's all you need to know, right there.

@artashes: don't forget that a "26mm equivalent" lens of a 1/2.3" camera is smaller than a 26mm equivalent lens of a 1/1.7" camera. thus the f1.8 opening is smaller too. do the math. it is not as bright as the current f1.8 - 1/1.7" lot - it's closer to the brightness of a f2.4 on a 1/1.7"

In reply to:

Timmbits: Don't let the f1.8 number fool you! For all you guys who think that f1.8 is a big deal with a 1/2.3" sensor, it is equivalent to only f6.4 on an aps-c sensor camera.

According to the link below, you would need a f0.5 on a 1/2,3" sensor like this one in order to compete with an f1.8 on an aps-c sensor.

And we're not even comparing to FF (which is the more common reference).

Here is a very useful link for everyone in this forum:
http://www.cambridgeincolour.com/tutorials/digital-camera-sensor-size.htm

Anyways, I realize that this is a high-end in the low-end cameras, and these comparisons aren't really relevant to it't target consumer market.

Just putting things into proper perspective here, so we can all understand what we are looking at.

@TOMEK: you are way out of your depth!
on a APSC, you could have f6 as an equivalent to the f1.8 on a 1/2.3" sensor! And you could use a much much faster shutter speed on the APSC at f3.5 than on this one at f1.8.

You guys don't get it do you?
FIRST, if you were even able to understand the link I sent, you would see that it allows you to also compare with a 1/17"!
SECOND (@PaulRivers) pretty much ALL the current enthusiast compacts have a better lens than this (because with a 1/1.7" the lenses are larger, thus their f2 or f1.8 opening is larger), so there really is no currently produced compact enthusiast with a worse lens.
THIRD:@all It's not just about DOF! Also relative brightness! ie: light gathering area of the sensor, coupled with the opening (this smaller lens divided by 1.8 in this case).
FOURTH: @some of you (you know who you are), you are making EXACTLY the same mistake you made when you bought your Q10: drooling over something smaller and cheaper thinking it's better.
...AND FINALLY it was just an FYI so that neophytes who are reading your myopic comments can get some TRUE FACTS and and get a better understanding of the compromises versus, say, an LX7 for example.

GeraldW: Hey Timm, lighten up. There are a few 1/2.3" sensor cameras around that do quite well up to ISO 800, and with the fast lens, that will seldom be needed. What cameras? Panasonic FZ150, FZ200, and ZS15, Canon SX230HS, SD4000IS, Pentax Q.

The Sony RX100 as a competitor isn't valid, as the street price in the USA will be 2:1. It won't sell unless it's under $300. The Canon S110 is valid as a competitor, and Olympus would seem to have chosen a faster lens to offset the larger sensor; but slower lens, of the S110. At full zoom, the XZ10 has a 2 stop advantage.

As far as DOF control, I think it's funny that what was considered a drawback 50 years ago is now touted as a feature. I started as a serious hobbyist in 1955, and somewhere along the way, "selective focus" became a new way to compose. For many situations, a large DOF is an advantage.

This camera is obviously not for you, and maybe not for me (I have an S90 and a G15); but I can see a number of valid uses for it.
